Dual Diaphragm Vacuum Pump w/ Brushless 24V DC Motor+Controller KNF N813.3 OEM

Description: Dual Diaphragm Vacuum Pump w/ Brushless 24V DC Motor+Controller KNF N813.3 OEM Dual diaphragm vacuum pump units made by KNF Neuberger in the USA. These are powered by a 3 phase brushless DC motor. They feature a built-in, adjustable-speed motor controller that is powered by 24V DC and has remote start and speed inputs as well as a tachometer output. Note that our latest batch of these have fairly short leads as shown. We have a few with longer leads available by request. We have bench tested each of these units. We configure the motor controller to auto-start and use the on-board trimpot for speed control. These ship configured to run the pump motor at full speed. You can turn the trimpot clockwise to reduce the motor speed which will reduce the noise, vibration and also the flow rate. These are configured with 2 independent pumps. Each inlet port has a manual valve and a quick release fitting for 5/32" OD tubing. The outlets have a silencer installed for quiet operation. It is possible to reverse the ports and use this for pressure rather than vacuum or plumb the pumps in series / parallel for higher flow / vacuum. The black pump bodies can be removed and re-installed rotated by 90 or 180 degrees to facilitate tubing routing. Note that the inlet and outlet ports have G 1/8 threads. Forcing a tapered NPT threaded fitting may break the plastic pump housing. These are an OEM version of a KNF model N 813.3 AN.29DC-B. Full specs can be found on the KNF website (search for 'KNF N 813').
